Title: Process for the destruction of organic  waste material
Inventor: HALLETT DOUGLAS J
IPC: A62D3/38
Filed: 1987-08-07
Abstract: A system for the destruction of organic waste material such as halogenated organic compounds, e.g., PCB's and related waste organic matter, comprises subjecting the waste material to reduction with a gaseous reducing agent, preferably hydrogen, at a temperature above about 600°C and thereafter subjecting the hot reaction mixture thus obtained to oxidation with a gaseous oxidizing agent at a temperature above about 1000°C. The combined reduction followed by immediate oxidation is effective in achieving substantially complete breakdown of the halogenated compounds to substantially non-noxious gases. The system includes a reduction vessel wherein hydrogen is used directly in intimate mixing relation with the pulverized waste material, and after completion of a residence time sufficient to reduce the organic compounds, the gaseous by-products pass to an adjacent combustor for oxidation therein.

Abstract: Preheatable molded refractory insulat­ing liners and methods of use thereof for lining vessels, such as hot tops, ladles, tundishes, troughs, and pipes, etc., which serve to transfer molten metals, such as ferrous alloys, are disclosed. The preheatable liners are suitable for developing effectively the required hot strength needed for casting molten metals at both vessel pre­heat temperatures and casting temperatures. The preheatable liners additionally possess the needed hot strength during the range of casting temperatures as are experienced in the metal making industry. The preheatable molded refractory insulat­ing liners comprise a liner structure of predetermined shape, the liner structure comprising a molded uniform mixture containing a particulate refractory component comprised of zircon and MgO refractory grain and a binder thereof wherein the zircon and MgO refractory grain are in amounts proportioned such that the hot strength is developed at vessel preheat and metal casting temperatures which are in the range of about 1900°F. to about 3000°F. when such liners are heated for sufficient periods of time.

Abstract: A flow transducer for producing a pressure differential responsive to rate of fluid flow comprises:- a housing (10) forming a flow passage (11a, 11b) for the fluid; said passage (11a, 11b) having disposed therein a parallel throat (13) which enlarges in the downstream direction into a chamber (14); a closely fitting yet freely sliding piston (16) disposed within the chamber and having an axial opening (18) for the flow of fluid; a valve member (19) of substantially conical form located and supported in the chamber (14) for obturating the upstream end of the said axial opening (18) when there is no flow; the said conical valve member (19) extending the the downstream direction nose first into the said axial opening (18) to provide a variable annular orifice (21) for fluid flow, the area of said orifice (21) increasing progressively with increasing axial displacement of the said sliding piston (16) in the downstream direction; an axially extending coil spring (23) for biasing the sliding piston (16) in an upstream direction to tend to reduce the area of the variable annular orifice (21) formed between the piston (16) and the valve memeber (19); the housing (10) having two pressure tappings (24a, 24b) therein at positions respectively upstream and downstream of the variable annular orifice (21) for the detection of a pressure differential induced by fluid flow; the said upstream pressure tapping (24a) communicating with an annular chamber (25) surrounding the throat (13); a plurality of radial holes (26) in an annular arrangement opening from the annular chamber (25) into the bore (13) of the throat for the detection of the upstream component of the said pressure differential, the said radial holes (26) being all of the same diameter and in the same axial position relative to the throat (13). 
     The housing (10) is made in one piece to minimize cost and to avoid possible leakage and fatigue problems such as are commonly encountered in high pressure hydraulic service. 
     Connecting means (28, 29) are provided at the upstream and downstream ends of the housing in the form of internal screw threads. These threads are of standard size having regard to the maximum flow capacity of the transducer and of the system in which it is fitted; making them internal (as opposed to external) screw threads maximizes the possible internal bore size of the housing for the containment of the working parts of the transducer mechanism and allows of the provision of flow passages of optimum size. 
     The valve member (19) is of simple frustro-conical form which has the effect of producing a roughly linear relationship between rate of fluid flow and pressure differential. If it should be necessary to produce some other relationship between these variables the longitudinal profile of the valve member (19) may be suitably modified; such a modification might be required were a more exactly linear relationship be necessary for instance.

Abstract: A laminated metal structure and a method of hard-surfacing stainless steel base metals are herein provided for resisting wear of steam turbine components at elevated temperatures. The laminated metal structure employs a buttering layer, sandwiched between the stainless steel base metal and a hard-surfacing layer. The buttering layer consists essentially of nickel or a nickel-based alloy and is selected to have a coefficient of thermal expansion which is between that of the base metal and that of the hard-surfacing material. This improved structure produces a relatively crack-free deposit that can provide greater service life for turbine components with less downtime due to repairs.

Abstract: A sheet made from a foamed polystyrene resin which is heat-shrinkable in one axial direction and has a heat-insulatingness is prepared. A printing process is applied to this sheet to produce a label. A container made from a thermo-plastic resin is covered with said cylindrical label and is put in a furnace in order to heat-shrink the label to be fitted on the container. 
     The container with the label manufactured in accordance with the present invention has a superior heat-insulatingness, and thus can maintain the temperature of water contained therein for a longer time. Also, when it is used in a electronic-range, a temperature of an outer wall surface of the container can be prevented from increasing, and thus the container can be held by a bare hand even immediately after cooking.

Abstract: The automatic compensation system, denoted by the abbreviation AFC, is a monobloc assembly which is totally insensitive to turbulence. According to the first part of the improvement, the system consists of two force sensor-comparators (1) mounted in series and providing for the fully automatic adjustment of the compensator as a function of the thrusts produced on the flywheel or rudder control bar whatever the attitude, height or speed. The system is completely adapted to the kinematics of the control circuits, whether rigid or cabled. The AFC is completely insensitive to three-dimensional accelerations and is noteworthy in that it also forms the basis of the system for validating orders given to the throttle control through the automatic control system which is the subject of the second part of the improvement and is denoted by the abbreviation AED. This automatic control system consists of a memory disc with double recording speed and transfer sectors allowing optoelectronic power regulation which is insensitive to turbulence for each memorised speed in a range from the initial approach speed (1.2 VS1) to the speed that must never be exceeded (VNE). <IMAGE>
